Research direction

Start by tracing the Eclipse plug-in's code-completion handling for MapStruct enum mappings and compare the paths for @ValueMapping and @ValueMappings. Reproduce the reported difference, then verify that completion works for both annotation forms.

Description

Hi,

I noticed that the code completion works fine with both @Mapping and @Mappings for object mapping. In the case of enum mapping, code completion works only with @ValueMapping, but NOT with @ValueMappings.

Regards,

Wayne
